We describe a new way of obtaining a radiation pattern that has equal minimum levels of the linear array antenna. By using this method we simultaneously control both the minimum level of the sidelobe and the level in arbitrary directions in the radiation pattern. The radiation pattern obtained with this method is almost isotropic. The radiation pattern is obtained by controlling only the amplitudes of the currents. The amplitudes of the currents are designed using digitally controlled attenuators. As these attenuators can be accurately changed in steps of 0.3 dB or less, the resulting quantization error will affect the radiation pattern. The effects of quantization error on the radiation pattern are thus verified.
